This invention relates to an ink applicator especially adapted for applying ink to a glass for the making of finger-prints, and hasyfor the primary object the provision of a device of this charac ter which will contain a supply of ink used in the making of finger-prints and'ameans for dis'- charging the ink on the glass as desired and :a roller for distributing the deposited ink overa selected portion ofthe surface of the glass without the hands and fingers ofthe operator coming in contact with the ink and becoming'soiled thereby. l With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of-parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation illustrating an'ink applicator constructed in accordance with my invention and showing the same at rest on a support.

Figure 2 is a side elevation of the applicator showing the device positioned for the depositing of ink on a surface.

Figure 3 is a side elevation illustrating the ink applicator positioned for the spreading of the ink on the surface.

Figure 4 is a longitudinal sectional view illustrating the ink reservoir of the applicator and the means of placing the ink under pressure within the reservoir.

Figure 5 is a fragmentary vertical sectional view illustrating the control means or valve for the release of the ink as needed.

Referring in detail to the drawings, the numeral 5 indicates a frame consisting of parallel arms 6 and a connecting portion 1. An axle or shaft 8 is journaled in openings provided in the arms 6 adjacent the free ends of the latter and 1 has mounted thereon a roller 9 constructed of rubber or any other material suitable for the purpose.

A handle 10 is formed on the connecting memher 1 intermediate the ends of the latter and is of hollow formation to provide an ink reservoir II. The reservoir opens outwardly through the 5 free end of the handle as well as opening outwardly through the connecting member 1 of the frame. The free end of the handle is reduced and screw threaded to be received within a cap l2. A gasket I3 is arranged in a recess within 55 the free end of the handle to engage the cap for sealing the latter onto the handle to prevent leakage of ink between theha'ndle'and'cap. The

cap [2 is provided with a recess l4 which communicates with the reservoir I l and seated in the recess is a coil spring l5,'one end of which is in v the form of a shank l6 and has secured thereto a piston-like member I'I equipped with a suitable washer'lii thathas frictionalcontact with the walls of the reservoir.

The spring I5 is of the expansible type for the purpose of placing 10 the inkin the reservoir under-pressure;

The end of the reservoir II which opens out wardly through the connecting-member 'l of the frame 5 is connected with a pipe'or tube I'Q'and :the latter connects with'a cylinder 20 above the lower end thereof and also "acts as .a support or attaching medium for the cylinder onto the frame 5. The upper end of the cylinder is closed by a removable cap 2| through which operates a stem 7 22 of a plunger type valve 23. The plunger type 20 valve is spring influenced by a coil spring 24 mounted on the stem between the plunger type valve and the cap 2| and normally acts to position the plunger type valve to close the pipe or tube 19 to the cylinder. 25

An operating lever 25 having a thumb piece 26 is pivotally mounted on a post 21 carried by the handle adjacent the frame and has a pin and slot connection, as shown at 28, with the stem of the plunger type valve so that by pressing on 30 the thumb piece 26 the plunger type valve will be made to move to open the tube or pipe 19 to the cylinder for the purpose of allowing the ink to flow into the cylinder in a desired amount. As soon as pressure is released on the thumb 35 piece 26, the spring 24 acts to restore the valve 'in a position to close the pipe or tube l9 to the cylinder and consequently cut oil the flow of ink to said cylinder. l

A pair of legs 29 is formed on the frame 5 or the connecting member I thereof and coact with the handle in supporting the device on a surface, as shown in Figure 1, with thelower end of the cylinder and the roller spaced from said surface. By lifting the handle upwardly the frame will fulcrum on the legs bringing the cylinder into engagement with the surface with the roller still spaced from said surface. Ink may then be applied to the surface by pressing on the thumb piece, the ink flowing from the lower end of the cylinder onto a restricted area of the surface. By lifting the handle upwardly to a. greater degree, the roller contacts the surface and the cylinder moves away from said surface so that the roller then may be moved over the ink and surface for the purpose of distributing the ink on the surface.

It is believed that the foregoing description, when taken in connection with the drawings, will fully set forth the construction and advantages of this invention to those skilled in the art to which such a device relates, so that further detailed description will not be required.

Having thus described my invention, What I claimisf.

1. An ink applicator comprising a frame,"a

handle providing an ink reservoir carried by said,

frame, a fulcrum means on said frame and edactive with the handle for the support gf the frame on a surface whereby the elevation of the handle will pivot the frame towardsthe surface;

ink dispensing means connected withthe harrdle for discharge of ink on the surface after a move} ment of the frame towards the surface, and
